根据压力模拟分析和其他研究人员收集的实验数据，给出了不同环境气压下池火燃烧速率的关系。理论分析表明，对于直径从10 cm到50 cm的明火，燃烧速率随海拔高度的增加而线性下降。在合肥和拉萨进行的两次燃料池火灾实验以及其他研究人员的数据也证实了这一关系。实验结果表明，尽管压力模拟分析因忽略了燃烧机理而或多或少地不准确，但压力建模分析仍然是预测不同环境压力下池火燃烧关系或规律的良好方法。
According to pressure modeling analysis and experimental data collected by other researchers,the relationship of pool fire burning rates under different ambient atmospheric pressure was presented.The theoretical analysis showed that for open pool fires with the diameters from 10 cm to 50 cm,the burning rate decreased linearly with the increased altitude.This relationship was proved by two fuel pool fire experiments conducted in Hefei and Lhasa,and by data from other researchers as well.The experimental results show that despite inaccuracy more or less due to ignoring combustion mechanism,the pressure modeling analysis is still a good method for forecasting the relationships or rules of pool fire combustion under different ambient pressures.
